keyval2e – A lightweight and robust key-value parser

The pack­age pro­vides lightweight and ro­bust fa­cil­i­ties for
cre­at­ing and man­ag­ing keys. Its ma­chin­ery isn’t as
ex­ten­sive as that of, e.g., the
ltxkeys pack­age, but it is equally
ro­bust; ease of use and speed of pro­cess­ing are the de­sign aims of
the pack­age.
